Yes. Several items in the selection are described as stackable—notably plastic pantry canisters and some modular food-storage containers—so they can be stacked for more efficient shelf or fridge storage.
They’re marketed for preserving and canning (salsas, syrups, sauces, fruits, vegetables), pantry storage of herbs and dry ingredients (flour, sugar), and general food storage, serving, and display.
Most bodies are made of glass or plastic. Lid and closure materials mentioned include wood, glass, polypropylene, and mason-style lids with separate bands.
